A client diagnosed with end-stage kidney injury receives continuous ambulatory peritoneal dialysis (CAPD). The nurse observes that the dialysate drainage fluid is cloudy. What is the priority intervention?

Choice A reason: Taking blood pressure in the left arm with an AV fistula risks compressing the fistula, potentially causing thrombosis or damage. This can impair dialysis access, leading to inadequate treatment and complications like uremia or fluid overload. Blood pressure should be measured in the opposite arm to protect the fistula.

Choice B reason: Keeping the AV fistula site dry is important to prevent infection, as moisture can promote bacterial growth. However, it is not the priority over ensuring fistula patency, which is critical for effective dialysis. Infection prevention is secondary to confirming the fistula’s functionality to avoid life-threatening dialysis interruptions.

Choice C reason: Wrapping the AV fistula in gauze is not standard practice unless post-surgical or infected. Excessive wrapping may obscure the site, hindering patency assessments, and could increase infection risk if not changed properly. This action is less critical than ensuring the fistula’s functionality for dialysis.

Choice D reason: Assessing the AV fistula for bruit (whooshing sound) and thrill (vibration) confirms patency, ensuring it is functional for dialysis. A non-patent fistula prevents effective toxin and fluid removal, leading to uremia, hyperkalemia, or fluid overload. This assessment is the priority to ensure life-sustaining dialysis can proceed without complications.

Choice A reason: Increased potassium intake is dangerous in ESRD, as impaired kidneys cannot excrete potassium, leading to hyperkalemia. This can disrupt cardiac membrane potentials, causing arrhythmias or cardiac arrest. ESRD diets require strict potassium restriction to prevent life-threatening electrolyte imbalances, making this modification inappropriate.

Choice B reason: Increased protein intake is often recommended in ESRD patients on hemodialysis to replace protein lost during dialysis and prevent malnutrition. However, it must be balanced to avoid excess urea production, which can worsen uremia. This is not the primary focus compared to phosphorus management in this context.

Choice C reason: Decreased phosphorus intake is critical in ESRD, as kidneys cannot excrete phosphate, leading to hyperphosphatemia. This causes vascular calcification and secondary hyperparathyroidism, increasing cardiovascular risk. Dietary phosphorus restriction, often with phosphate binders, prevents these complications, making it a key dietary modification for hemodialysis patients.

Choice D reason: Decreased calcium intake is not recommended in ESRD, as patients often have hypocalcemia due to impaired vitamin D activation and phosphate retention. Calcium supplementation or adequate intake is needed to prevent bone disease and secondary hyperparathyroidism, making this modification incorrect for ESRD management.
